Willa Jean is Howie's younger sister and causes a lot of trouble (in fact, she acts just like Ramona did when she was four). Howie's grandmother spoils Willa Jean, but doesn't like Ramona, making her watch Willa Jean and then blaming Ramona whenever she does anything wrong. Uncle Hobart shows up in Ramona Forever

A girl in Ramona's classes throughout the series, and one of the few that Ramona doesn't get along with.

- Only Known by Their Nickname: He's only refereed to by his real name in the series when addressed by adults. Even the narration calls him Yard Ape.
- UST: Well, in the sense that 9-year olds can have sexual tension. Ramona and Yard Ape both clearly have crushes on each other, but they don't want to admit it to each other, and the series ends before they're old enough to start dating.
